Sorcerer

Sorcerer: Metamagic

From 5th level, you know two metamagic options. You know three option at 10th level and four option at 17th level.

Whenever you finish a long rest, you can replace any metamagic option you know with another metamagic option.

Metamagic

Persistent Spell

When you cast a spell that targets only you and requires concentration, you can expend a number of sorcery points equal to the level of the spell to remove the concentration requirement from the spell. If you do so, the spell lasts for its full duration, and you have no further control over the spell.

The spell ends early if you use this metamagic option again during the spell’s duration.
